About December 15

December 15 serves as a profound milestone in the history of human liberty and law. In 1791, the United States Bill of Rights officially became law following its ratification by the Virginia General Assembly, establishing the fundamental protections that define American citizenship. This spirit of documentation is echoed in 1836, when a devastating fire at the U.S. Patent Office destroyed nearly ten thousand original patent records and thousands of physical models.

Beyond the halls of government, the day has seen remarkable scientific and cultural leaps. While the Soviet Union pushed the boundaries of the cosmos with its Venusian landing, the world of music was being transformed; in 1893, Antonín Dvořák’s legendary "New World Symphony" was given its first public rehearsal at Carnegie Hall. Whether through the expansion of civil rights or the exploration of distant planets, December 15 remains a cornerstone of human progress.
